The value of sufficient sleep can’t be overestimated, especially for busy college students. Researchers consistently find that not getting enough sleep can significantly affect how students function.
Lack of sleep has a negative effect on the regulation of hormones and other physiological processes, such as motor skills. Sleep deprivation is also linked to an increase in cortisol, more commonly known as the bodyâs âstress hormone.â And stress levels have an impact on weight, mood, energy level, immunity, and concentrationâso sleep is a key factor in studentsâ academic success.
Acute sleep deprivation is often associated with episodes of âmicrosleep,â or brief, uncontrollable periods of sleep lasting three to six seconds. â[They can] intrude upon wake at inopportune times, such as during a lecture,â says Dr. Michel Bornemann, a sleep medicine specialist and former codirector of the Minnesota Regional Sleep Disorders Center.
It can also be more serious. Dr. Bornemann points out that research shows driving after pulling an all-nighter is âvery similar to the impairment experienced when driving while intoxicated with alcohol.â
